The Galaxy Ace 3 has an adequate set of specs for the price, but neither its screen, software or performance match the Motorola Moto G's, which costs half as much. Unlike the Moto G though, the Ace 3 does offer 4G and expandable storage -- the only reasons to go for this phone over Motorola's

For pay as you go budget buyers, the Galaxy Ace 2 is a great all-rounder, with a dual-core chip and an excellent camera. It's not so competitively priced SIM-free or on contract so its appeal is limited. Android enthusiasts may be disappointed to hear it runs on Gingerbread software, rather than the newer Ice Cream Sandwich.

The Samsung Galaxy Ace Plus is a slightly souped-up version of the Galaxy Ace. It looks like a decent Android phone in its own right, though the Galaxy Ace 2 might prove a better choice if it doesn't wind up being much more expensive, as that phone features a bigger, higher-resolution screen.

Samsung's made the right sacrifices to keep the cost of the Galaxy Ace down. It has a relatively low-res screen and lacks the power to play Flash video, but this Android phone is packed with fun features and looks much more expensive than it is.
